Thanks to @FFeller, how helped me to automate a rendering of an object with the associated list of material. And Thanks to @Marty Fouts, how helped me with a script for renaming a rendered images with there associated materials. It works perfectly if the generated names are made by default. – link bellow – But I have many objects to render with the specific names, generated by a Compositing Output file, and the script looks for names like – 0000.png – and didn’t recognize names like – CUBE_ONE_0000.png – Knowing that I have a small knowledge of Python, can you please @Marty Fouts, help me to adjust the scripts. Images to illustrate my needs, hoping that I made it clear😊 Thanks a lot.
